STREET-SWEEPER..

SPECIFICATION forming part of Letters Patent No. 593,749, dated November16, 1897.

I Application filed June'l, 1897. Serial No. 640,667. '(No model) y .To@ZZ whom, .it may concern:

Be it known that I, JOHN Z. LEVY, a' citizen of the United States,residing at Apollo; in the county of Armstrong and State'of Penn'-Sylvania, have invented certain new and usel ful Improvements in StreetSweepers and Oonvcyers; and I do declare the following to be a'full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesaine, reference being had to the accoinpanying drawings, and lto thefigures of reference marked thereon, which form a part of thisspecication-`v This invention l usefulimprovements in street-sweepersand conveyors.

My invention relates to that class of streetsweepers in which the dirtis swept up ontoan endless conveyer by 'a rotatable brush 'and y.deposited in a wagon.

' Ihe invention consists in the novel construction and combination ofparts,l herein- 'after fully described and claimed. f

In describing the invention in detail reference is had to theaccompanying drawings,

' forming a part of this specifcation,and wherewagon and which in likenumerals designate like parts throughout the several views shown, inwhich- Figure l"`is side View of my improved Street-sweeper. Fig. 2 is aplan view of the .same with the conveyer removed. Fig. 3is

an enlarged perspective view of a portion of the conveyer.

In constructing my improved street-sweeper I provide a suitablerunninggear for the has revolving axles with the wheels made fastthereto, and upon this running-gear I attach a stout frame l, and uponone side of this frame I secure a pair of hinge-rods 2 and 3, whichextend parallel with the frame. Suitable antifriction-rollers 4 areattached to the upper side oftbe'frame and' at four different points,and upon these rollers is supported the box-bed 5, which is connected tothe said hinge-rods 2.and 3 by the hingeplates 5. Attached to the rearend of the wagon-frame and by the links and 7 is the inclinedconveyer-pan 8. At the lower end of this pan is formed a pair ofupwardlyex ltendedbrackets, which support the rotary brush 9. Attachedfast to one end of the gear-wheel l2 and chainwheel 13.

'end of the rotary-brush shaft.

relates to certain new and -which is mounted shaft of the said rotarybrush is the gear-pinion 10, and upon the side of the lconveyer-pan isformed a bearing, into which `is fitted a short shaft 11, vand upon thisshaft are secured the The said with the pinion upon the Upon the rearaxle is mounted the chain-wheel 14, and is connected to the chai-nwheel13 at the lower end of the conveyer-pan by means of the chain l5, so asto convey power to` the rotary gear-wheel meshes brush and rotate it inan opposite direction.

when the wagon 'is moved forward. At thev upper end of the conveyer-panand across the same are loosely tted a shaft 16, upon a pair of spiders17 and 18, and another shaft 19, which has a similar pair of spiders 2Oand 2l, mounted thereon. Mounted upon the said spiders is a conveyer,which consists of a series of links 22, 23, and 24, which are allpivotally connected together upon the rods 25. The said links 24 areeach turned over at right'angles at one end and have secured to them theconveyer-blades' 26.

:Upon the outer end of the shaft 19 is secured ai chain-gear 27, and asimilar gear 28 is arranged on the end of the rotary-brush shaft and areconneetedtogether by the chain 29', in order to transmit power from thebrush to the traveling conveyer. y

. The operation of myimproved device would be as follows: As the wagonis drawn forward the wheels, by the intermediate gearing, cause thebrush to rotate and up into the conveyer-pan,where the travelingconveyer catches it and conveys it up to the end of the pan, where itfalls into thewagon, and when the wagen has been loaded and transportedto the dumps the bed is shovedv forward suiiicient to clear theconveyer. It is then turned over and the contents dumped out and the bedagain placed in position:

Slight Variations and changes may be made in the detail parts withoutdeparting from the general spirit of my invention.

Having thus fully shown and described my invention, what I clairn' asnew, and desire to secure by Letters Patent, is v The combination with awagon, of the inclined links, the inclined conveyer-pan secured thereto,the transverse shafts at the upper and lower ends thereof provided'withsweep the material chain, the rotatable brush having a sprocketpinion atone end with which said chain engages, t-he oog-pinion at the other endof saidl brush, the pinion meshing therewith secured to a stud-shaft,the sprocket-pinion on said stud-shaft, the chain connected therewithand the sprocket-pinion on the wagon-axle with n which said chain isalso connected, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
